<h2>\boldmath</h2>

<p>The <tt>\boldmath</tt>
    <a href="declarations.html">declaration</a> switches to a bold
    math italic font; this causes letters, numbers, and
    <strong>most</strong> symbols used in math mode to be set in a
    bold type.</p>

<p>(In <a href="versions.html">LaTeX2e</a>
    <strong>everything</strong> in the formula is set in a bold font.)</p>

<p>The <tt>\unboldmath</tt>
    <a href="declarations.html">declaration</a> switches
    back to the normal math italic font.</p>

<p>Note, these commands should <strong>not</strong> be used in
    math mode. Thus the scope of the
    <a href="declarations.html">declaration</a> must include the
    math mode expressions to which you want it to apply.</p>

<p>If you want only part of a formula to be bold an
    <tt><a href="ltx-265.html">\mbox</a></tt> command is useful:</p>

<pre>
  <a href="ltx-115.html#math">\(</a> Regular formula + \mbox{\boldmath$ Bold part$} = 0 <a
        href="ltx-115.html#math">\)</a>
</pre>

<p>Both <tt>\boldmath</tt> and <tt>\unboldmath</tt> commands are
    <a href="fragile.html">fragile</a>.</p>
